[architecture] When to use multiple agents versus one agent with a large skill library

Default to a single agent with multiple tools. Only introduce multiple agents if you hit context window limits, need strict permission isolation, or require highly divergent system prompts.

Journey Context:
Engineers often map human org charts to agent architectures, creating a 'sales agent' and 'support agent'. This introduces coordination overhead, state synchronization errors, and routing failures. A single LLM with a unified context and tool suite is far more reliable for tightly coupled tasks because it eliminates handoff latency and context loss.
